Agency: Department of the Interior, Bureau of Reclamation, Reclamation Bureau
The Bureau of Reclamation, as the National Environmental Policy Act Federal lead agency, and the Contra Costa Water District, as the California Environmental Quality Act lead agency, have prepared the Los Vaqueros Reservoir Expansion Final EIS/EIR. Los Vaqueros Expansion is a proposed action in the August 2000 CALFED Bay-Delta Program Programmatic Record of Decision. The Final EIS/EIR evaluated two options for expanding Los Vaqueros Reservoir from its existing capacity of 100 thousand acre-feet (TAF). A 175 TAF expansion option would expand the reservoir to 275 TAF. This expansion option would be operated for environmental water management and San Francisco Bay Area water supply reliability. A 60 TAF expansion option would expand the reservoir to 160 TAF. This second option would primarily be operated to improve Contra Costa Water District (CCWD) dry year water supply reliability and water quality.
